Relationship between PCB & Integrated Circuit

The most important thing about electronic products is the circuit that drives each device. In the study of electronic knowledge, we often talk about circuit boards (PCBs) and integrated circuits (ICs). Many people cannot understand them correctly. They are completely unclear and cannot understand them correctly. The editor walks into this electronic world and helps you understand the connections between them and their respective characteristics.

What is PCB?

PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board.

The current circuit board mainly consists of circuit and pattern (Pattern), dielectric layer (Dielectric), hole (Through hole / via), solder resistant ink (Solder resistant /Solder Mask), and silk screen (Legend /Marking/Silk screen) , surface treatment (Surface Finish) and other components.

Advantages of PCB: high density, high reliability, designability, producibility, testability, assembly, and maintainability.

What is an integrated circuit?

An integrated circuit is a miniature electronic device or component. Using a certain process, the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit are interconnected together, made on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a tube shell , becoming a microstructure with required circuit functions; all components in it have structurally formed a whole, making electronic components a big step towards miniaturization, low power consumption, intelligence and high reliability. It is represented by the letters "IC" in circuits.

Integrated circuits can be divided into three categories: analog integrated circuits, digital integrated circuits and digital/analog hybrid integrated circuits according to their functions and structures.

Integrated circuits have the advantages of small size, light weight, few lead wires and soldering points, long life, high reliability, good performance, etc. At the same time, they are low in cost and convenient for mass production.

The relationship between PCB and integrated circuit

Integrated circuit generally refers to the integration of chips, such as the Northbridge chip on the motherboard, and the inside of the CPU are all called integrated circuits, and their original name was also called integrated blocks. PCB refers to the circuit board we usually see, and there are printed and soldered chips on the circuit board.

Understanding of the relationship between the two: the integrated circuit (IC) is welded on the PCB board; the PCB board is the carrier of the integrated circuit (IC).

Summary: To put it simply, an integrated circuit is a general-purpose circuit integrated into a chip. It is a whole. Once it is damaged internally, the chip will also be damaged. PCB can weld components by itself. If it is damaged, it can be repaired. Replace components. The above is some analysis of learning circuits, I hope it will be helpful to scientific researchers.
